TYPEWRITING-MACHINE.

Specification of Letters Patent.

Patented. Apr. 6. 1920.

7 Application filed October 1, 1918. Serial No. 256,462.

To all whom it may concern:

Be it known that I JOHN EDWARD OUoN- NOR, a citizen of the llnited States, residing at 1727 Lake street in the cit and county of San Francisco, btate of Ca ifornia, have invented a new and useful TypewritingMw chine, of which the following is a specification.

each key,

My invention relates to improvements in typewriting machines whereby entire lines may be printed without removing the fingers from the keys.

I accomplish this:

1st. By eliminating all unnecessary characters, such as small letters or signs which can be made i) the combination of other characters as, or example, the percentage sign and the exclamation point (1). This leaves only fifty characters which are arranged on the key board in the following order (see Figure 1, accompanying drawing):

2nd. Iiy arranging the characters on the type bars or type cylinders in conformity with the type ke 's, as described on page 1, lines 23 to 27 inc usive of this specification. (See specimen type bar, F .ig. 3 of accompnnyin drawing.)

3rd. n place of only one or two or three characters controlled by one key, in my in vention five characters are manipulated by (See Fig. 1 of accon'ipanying drawin 4th. F11 place of only one or two or three characters on each type bar or rows on each type cylinder, my invention has five characters on each type bar and five rows of ten characters each on each ty 'ie cylinder, thercby reducing the number of type bars to ten. (See Fig. 3 of accompanying drawing.)

5th. In place of small disks for keys, in my invention grooved levers adapted to the easy use of the fingers and thumbs of each hand are employed. (See No. 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 of Fig. l of the accompanying drawing. No. 18 Fig. 2 of the accompany ing drawing is a cross section of No. 5, Fig. 1.)

6th. In. place of from 28 to 84- keys, my invention has only ten. (See Fig. l of accompanyin r drawing.) The keys are desig" nated by t e character at the top of each, thus: 1 key; iii key; A key; F kc 1; y; 1) y; Um y; Z y; u( 71 key and 6 key and will be so designated in this specification. The fingers and thumb of the left hand are used exclusively to. con 1; $7,; ix; I? 1i the thumb and fingers of the right hand are exclusively used to control keys: P, U, Z, z) and 6. (See Fig. 1 of accompanyin drawing.)

7th. fiy employing knobs under each palm and operated by pressing down for spacing. (See Nos. 15 and i6 of Fig. l of accompanying drawing. Fig. 2 under No. 18 shows :1. cross section of the knob.)

When the finger 0r thumb of one hand is engaged in striking a ke the palm of the other should be used to space.

8th. By employing the feet to raise the carriage two spaces or lower it two spaces or move it forward two spaces or backward two spaces depending on the make of the machine.

Fig. 1 is a general view of the key board showing type keys, palm spacers and carriage shift keys; Fig. 2 is a cross section oF a type key above a cross section of a palm spacer; Fig. 3 shows a typebar; Fig. 4, the foot platform with heel and toe attach ments; Fig. 5 illustrates the operative relation of the parts. showing the slots and pulleys through whi h the cords r straps attached to the carriage shift levers and the front and back part of the operators t'cct pass.

In place of one or two shift keys worked by the finger, in my invention four shift keys are attached by straps or wires to the front and back part of each foot. (See Fig. 4 and Fig. 5, showing foot apparatus and Nos. 1,2, 13 and 140i Fig. 1, Fig. 5, showing shift ke 's.) Shift keys Nos. 1 and 2 being on the eft side are controlled by the left foot ([1, Fig. 5) and shift keys Nos. 4 and 5 being on the right Shit are controlled by the right foot (It. Fig. 5).

The feet rest on a platform (see Fig. 4 and Fig. 5 of the accompanying drawings), raised an inch or so from the floor and firmly attached thereto. The toe stra (No. 28 of Fig. 4 and No. 28 and 28 of *ig. 5) attached to the front part of each foot passes down through a slot in the platform, through a, pulley (27) Fig. 1 and (27) and Fill (27") lig 5 and then up and out a few inches in front of the foot and then to its proper shift key on the typewriter Wllit'li is No. 2 for the left and No 4 for the right toe (see Fig. 5).

The heel strap attached to the rear part of the foot (see #2:) Fig. -l and #23 and 23" Fig, 5 of the accompanying drawing) also passes down into th platform, under the foot, through pulleys #21 and #25 (sets Fig. 4 and Fig. 5, #24 and #2? and #24" and #25) and then romes out in front of the toe slot. It is then attarhed to its proper shift key whirl] is No. 1 for the, left heel and No. 5 for the right. heel.

The ehararters are printed in the follo\\ ing' manner: "A by raising left heel and pressing down A' key: llf b raisino left toe and pressing down i\" key: by pressingdown A l\'e with feet Hat on th platform: "'l b raisin right toe and pressing down A' key and HT b raising right heel and pressing down he "lhe other ehararters on the other keys are print ed in a similar manner. that is. all the lirst or top rharaeters on the key board by raising the loft heel and pressing down the he): the seeond eharaetor on eat-h key. by raising the left toe and pres zi|1g down the key; tho third or middle eharaeter on eaeh key. by pressing down the key with both feet Hat on the platform: tho fourth or next to the bot tom eharaeter on eaeh key, by raising the right toe and pressing down the ke and the fifth or bottom oharaeter on (tlt'll key, by raising the right heel and pressing down the key.

I am aware that prior to my invention t \'pe\rriting niaehines have been ronstrurted with typebars manipulated by linger keys and typebar levers. l am also aware that prior to my invention spacing merhanisms have been invented. l am also aware that prior to my invention typewriting maehines have been made with movable earriages operated by shift keys and shift levers. I therefore do not elaim sueh a eombinat'ion broadly; but

I do claim:

1. In a typewriting machine the eombination of a foot platform with three holes or slots in front of the SPttt'QH for the operators feet and one hole or slot llttlik of the spaces for the operators feet, the fixed pulley underneath the platform and between the two slots in front of and nearest the toe, the farther downward projeeting lixod pulley undern *ath the platform and under the outermost hole or slot in front of the operators feet, in eonjunetion with a strap or cord attached to a typewriter shift key or shift |e\ er passing down through the said middle slot in the foot platform, thence through the fixed pulley underneath the platformsaid pulley bein; plat-ed between the two slots llfOl'tHtlilllllllH'Q and up and through the slot or hole in front of and nearest the front part of the operatofs foot to \vlll 'll it is adapted to be, Zltlilt'lltfl, substantially as desrribed.

.3 lo a typewriting marhine the rombina tion of a foot platform with three holes or slots in front of the spaces for the o 'ierator s feet and one hole or slot ark of the spares for the operatofs feet, the fixed pulley underneath the platform and between the two slots in front of and nearest the toe, the farther downward projeeting fixed pulley underneath the platform and under the outermost hole or slot in front of the oporatorls feet, in oonjunotion with a strap or cord attaehed to a typewriter shift key and shift lever passin g down through the outermost of the three holes or slots in front of the operatofs foot and in the said foot platform, them-e through the fixed and farther downward projecting pulley underneath the said platform thenee through the pulley under the platform and under the operators heel, thenee up and out to the bark part of the operators foot to whit-b it is adapted to be nttarhed, all substantially as stated.

3. In a typewriting maehine the combination of a key board with typobar levers and typebars, palm spacers and shift keys and shift levers attaehed to a movable earrings in eonjunetion with a foot platform with slots, pulleys and straps and attarhments for the front and back part of the operators feet, all substantially as set forth and deserilicd.
